[0004] At this stage, the installation of the anchor needs to first pass the steel wire rope through the holes of the fixed anchor one by one, and then place the anchor clamp piece by piece in each hole step by step, and then press and fix it. This installation method makes the anchor clamp The sheet is easy to fall off during installation and needs to be installed repeatedly, but at this stage there is no suitable anchor installation tool to replace manual installation, and manual installation can only be installed one at a time, which is a waste of time and inefficient

The invention discloses a quick mounting type pre-stressed anchorage device for concrete buildings. The quick mounting type pre-stressed anchorage device comprises an anchorage device clamping pieces,a fixed anchorage device, a moving anchorage device and connection bolts. The fixed anchorage device is provided with a plurality of rebar through holes and threaded blind holes, the moving anchoragedevice is provided with a plurality of square holes and a plurality of through holes in one-to-one correspondence to the threaded blind holes, bottoms of the square holes are provided with round through holes, and moving plates are arranged on left and right side walls of the square holes. Two threaded rotating columns are arranged on one side of each moving plate, tail ends of the threaded rotating columns are provided with winding columns, the top end of each threaded rotating column is provided with an auxiliary groove, the threaded rotating columns are arranged in the moving anchorage device, the winding columns are fixedly connected with retractile lines which penetrate springs I to be fixedly connected to the moving plates, and tail ends of the connection bolts are provided with external threads. The quick mounting type pre-stressed anchorage device enables quick mounting of multiple anchorage device clamping pieces and is suitable for different types of anchorage device clamping pieces.
Description
technical field [0001] The invention relates to a quick-installed prestressed anchor for concrete buildings. Background technique [0002] Anchorages are widely used in highway bridges, railway bridges, urban overpasses, urban light rail, high-rise buildings, water conservancy and hydropower dams, port terminals, tunnel mine top anchor tops, subways, large containers and ships, sleepers and other fields. [0003] Anchors refer to the permanent anchoring devices used in prestressed concrete. They are anchoring tools used in post-tensioned structures or components to maintain the tension of the prestressed tendons and transfer them to the interior of the concrete. [0004] At this stage, the installation of the anchor needs to first pass the steel wire rope through the holes of the fixed anchor one by one, and then place the anchor clamp piece by piece in each hole step by step, and then press and fix it. This installation method makes the anchor clamp The pieces are easy to ...
